    Hmm. On x86-64, pte_unmap() is a no-op. So moving it around should not
    matter one whit. We don't even have a debug mode to turn it into some
    kind of "check that we use it properly in an atomic region" which we
    _could_ do.

    Can you send me the messages you saw without that patch? There's
    something odd going on here. I don't like the fact that the patch
    apparently makes a difference for you. It shouldn't.
